How should ginseng seeds be treated before flat-ground planting?

How should ginseng seeds be treated for flat-ground planting? Please explain the method. Before planting ginseng, you can refer to the following methods for treatment: after the water seeds are dried until the skin turns white, spread them in sunlight at a temperature of around 25°C and turn them for 30 minutes; this uses ultraviolet light to kill bacteria on the seed coat. Mix weathered sand (river sand also works, but it has a high bacterial content...) with ginseng seeds at a ratio of 5:1, keeping moisture between 15% and 18%, that is, it forms a ball when squeezed in the hand and breaks apart when released. Store the mixed ginseng seeds with moderate moisture in a jar or wooden box, or dig a pit in ground that does not accumulate water, wrap it with mesh netting, and build a rainproof and sun-shading shelter above. Before the seeds crack, control the temperature at 18°C-20°C. After the cracking rate reaches 80%, lower the temperature of the seed storage container to 13°C-15°C. Too high a temperature and too much moisture easily cause seed rot. Ginseng seeds stored in sand should be turned once every 10-15 days to ensure consistent moisture in the container. When moisture is low, supplement with a warm water spray; when moisture is high, dry them in the air promptly.
